Nah, I don't really have an issue with it. We're talking about the hardest pursuit in cricket, for which the guy has natural ability. The amount of guys who have been over coached in spin bowling... I think what he's done is really smart.
He's probably lucky in a way that he can hold his spot as a batsman in the Shield side. If he was a leggie just around the shield squad, he couldn't do that; take a break from bowling leggies and just let it come back with a natural flow. He'd have to keep on bowling, trying to establish the things that all these coaches are telling him to do, and end up trying to bowl with someone else's action. Or he'd take the break, be cast aside by the powers that be and have everyone talking rubbish about why he was no longer in the state squad.
